There is another subtle advantage to using an
SSB generator to generate AM. Assuming
that the AM is generated using a (unbalanced)
balanced modulator, overdriving the system
with slightly excess audio does not generate
the horrible splatter that results from overmodulating
the usual "plate modulated" kind of transmitter.
If the resulting AM signal is applied to a linear
amplifier to get the power level up, the of course
that amplifier must be able to handle the positive
peaks but that is, in my mind, a separate issue.
